BALL-BEARING PULLEY.

SPECIFICATION forming part of Letters Iaten't No. 761,477, dated May 31, 1904.

l Application filed J anuaryZ, 15504,' Serial No. 190,429.- (No model.) I

T0 all whom it may concern:

Be it known that I,WILLIAM C. HABICHT, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Ball-- Bearing Pulleys, of which the following is a specification. f'

My invention relates to an improved construction of ball-bearing pulley, and has forv its object to provide a pulley of simple and ,durable construction the parts of which may be parts which comprise the bushing portion of' the pulley, and Fig. 4 shows an end elevation of one of said bushing parts.

In the drawings, a designates the rim or body portion of the pulley having the usual circumferential channel or groove b and also having a center opening c and an interiorcircular flange Zin said opening. The opposite sides of this flange are each curved or rounded to form a recess c. center opening c of the rim or bodyiportion, and said bushing comprises two parts f and g, each of which is provided with an exterior outer ange f and g and an interior annular Harige f2 and g2. An annular channel]L13 and g3 is provided with each o f the bushing parts between the outer and inner iianges f and f2 of one part and g and g2 of the other part, and each of these annular channels f3 and g3 are semicircular in cross-section. The bushing part-l fis also provided with a central opening ft, and the mouth of said opening on the outer side (see Fig. 4) is provided with a beveled surface e'.

A bushing fits into thel j The bushing part g is provided with a cir-v cular hub-flange which projects laterally from the inner flange g2, and said hub-flange passes through the openingf4L of the bushing part f, and the face it of said hub-fiange is turned over or riveted down against the beveled surface o' of the bushing part f and the two parts secured together within the rim or body e. Two series of balls j and j have position in the annular channels f3 and g3. When vthe two bushing parts ,are in position,

` the hub vof one fitting within the other, the

inner flanges f2 and g? confront each other and the circumferential surface of said two flanges register with the central flange Z of the rim or body.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A ball-bearingpulley having a body provided with an interior circular flange; a bushing comprising two parts each of which is provided with two flanges with an annular channel between said two flanges and also having means for securing the two parts together with their inner flanges confronting each other.

v2. A ball-bearing pulley having a body provided' with an interior circular flange; a bushv ing composed of two parts, each part of which has two flanges, one of which latter is smaller in diameter than the other, and the smaller flanges of each bushing part confronting each other and having position within the interior circular flange of the body and said bush- 'ing parts each also having an annular channel between its larger and smaller flanges.

In testimony whereof I aix my signature in the presence of two witnesses.
